Transmit Configuration Registers (TX_CONFIG_1 and
TX_CONFIG_2)
The two transmit configuration registers control which internal modules will transmit data through the
PPM. Each of the configuration registers contains eight separate 2-bit wide bit fields. Each of the 16 fields
controls a multiplexer that selects a 1-bit channel from an internal module to the PPM transmit data
register. See
for more information on channel control and setting the channel values.

CM and STR will only effect PPM transmit/receive when PPM is
configured for SPI mode. In TDM mode transmit/receive will be
continuous regardless of the values of CM and STR bits.
